For functionality, it's not important. However, for CE compliance, it is, because the ground wire is on the pictures of the device in the photo-documentation of the CE screening at TÜV Rheinland. I am only allowed to sell the unit in the form that I've ran the screening, which is why I have to a) recommend putting the RF shield back on and b) recommend to use the ground wire.
